| Abstract: | Hydrogen addition will influence the characteristics of spray atomization and combustion of diesel oil,and emission characteristics of hydrogen/diesel engine.The modified KIVA-3V codes was used to study the characteristics of NOx and particulate emission of hydrogen/diesel engine and the effect of hydrogen addition on the emissions of NOx and particulates.Results show that at engine low load condition,the NOx and particulate emissions of the hydrogen/diesel engine are lower than those of diesel engine.At hi... |
